    After hearing Zhuang Jianye's words, Aziz couldn't help but be stunned for a moment, but the next moment he unconsciously raised the corners of his mouth and shook his head: "Mr. Zhuang, I can admit that Ascendas Group is the global leader in the laser field, but  There is a consensus in the industry that I think you should be aware of, that is, laser processing technology is not suitable for micro-precision processing in the aerospace field."

    After a pause, the middle-aged man next to Aziz immediately handed over a bottle of soda with respectful hands. Aziz took it indifferently and took a sip gracefully. Then he cleared his throat and continued: "I  It is undeniable that under extreme circumstances, lasers can be used to process qualified products that meet the conditions, but this single measure is not replicable, and in layman's terms is not in line with industrial mass production"

    Aziz is indeed a senior expert who has been in the European aviation technology circle for most of his life. Whether it is theory or practice, his knowledge and experience are impeccable.

    Not to mention anything else, but for laser processing, which is not a niche in the field of aviation manufacturing, but it is definitely not a mainstream manufacturing process, Aziz can speak clearly and clearly, which fully shows his attainments in aviation technology.  It's quite impressive.

    And aviation experts from the United Arab Emirates and Algeria, who had gradually gathered because of Aziz¡¯s dialogue with Zhuang Jianye, all nodded in agreement after listening to Aziz¡¯s words.

    Not to mention outsiders, even a few of the air force experts in the army who accompanied the head of the headquarters agreed with Aziz's statement, frowning and looking worried.

    So Aziz¡¯s statement is not only correct, but also very correct. In a sense, it has even become a recognized consensus in the industry.

    This is indeed the case in implementation. Laser processing technology, especially precision hole processing, does have incomparable advantages over other processing methods, such as simple operation, low cost, and convenient efficiency.

    But it also has its own insurmountable shortcomings, that is, the wavelength of the laser is too large and the pulse is too high, resulting in too high surface temperatures of the drilled parts, which can easily lead to excessive internal thermal stress around the process holes, causing the surface to be recast into many, thick or even  Fine cracks will form around the process holes.

    Civilian components that do not require high structural strength are not that big of a deal, but in the aviation manufacturing field with strict requirements, excessive internal stress, not to mention cracks, may cause structural fatigue of the components and a sharp reduction in their lifespan, threatening the flight safety of the entire aircraft.  .

    With more sophisticated aero engines, these shortcomings are even more intolerable.

    Because of this, laser processing technology is generally used for cutting or welding in the aviation manufacturing industry. Of course, additive manufacturing has recently been added.

    But no matter which one it is, it is far from hole processing, especially micro-precision process hole processing.

    Among other things, when Ascendas Group used to process the film cooling holes in turbine blades, it did not use lasers. Instead, it used a manufacturing technology called electrochemical drilling. The advantage is that it can complete the film cooling holes in one go.  Processing without doing other processing.

    The problem is that the electrochemical drilling process has been the production technology of Ascendas Group five years ago. Now that the Soviet Union has disintegrated and the world structure has changed, Ascendas Group must embrace the old almanac to leap into the next century, and cannot compete with  Keep up with the times?

    "Well, Mr. Aziz, and all the experts, let's go to our wc-8 honeycomb combustion chamber production workshop to see if our nb-6600dl ultra-precision laser hole making machine can  Realize what you call industrialized mass production.¡±

    After Aziz used his elegant royal intention to popularize the knowledge that laser processing is not suitable for precision hole processing recognized by the world aviation industry, Zhuang Jianye did not refute, but smiled and made a suggestion, and then turned to the other side.  Go to the door.

    "Your Highness Abdullah, His Highness Mahmoud, why don't we follow him and have a look?" Seeing Zhuang Jianye leaving, the head of the headquarters immediately sent an invitation to the two real speakers.

    How could Abdullah and Mahmoud refuse the head of the headquarters, a real boss? They nodded immediately, chatted and laughed with the head of the headquarters and slowly left with Zhuang Jianye.

    Seeing the two highnesses leaving, Aziz and others had no choice but to follow them even if they didn't want to go. What's more, they were also curious about what kind of equipment the nb-6600dl ultra-precision laser hole making machine Zhuang Jianye mentioned was.  Can it really break the consensus that has been true for many years in the aviation industry?

    So one by one they hurriedly followed, and after walking around for about five or six minutes, they finally arrived in front of a factory building made of reinforced concrete. After that, they went through several procedures such as dressing up, dust removal, disinfection, and sterilization.  , when everyone entered the workshop, they were all wearing dustproof clothing and goggles. From a distance, they looked like they were carved from the same mold.Sample.

    However, Aziz and others not only did not find it troublesome, but upon entering the workshop, they were shocked speechless by the two extremely sophisticated equipment in front of them.

    The equipment in front of me with the words nb-6600dl painted on the facade is about 5 meters long, about 3 meters wide, and about 2.5 meters clear. The left side is the processing area, where there are five wc-8s open in a row.  A honeycomb combustion chamber flame barrel, on which a flexible laser is facing one of the flame barrels to accurately drill process holes one by one using a high-energy laser.

    However, this is not surprising to Aziz and others. After all, they have seen a lot of this kind of laser drilling equipment in Europe and the United States, and even some processing centers in their own country have laser processing equipment.  What made them really incredible was the observation window on the right side of the device that was used to observe the operation of the internal mechanisms of the device.

    You really don¡¯t know it until you look at it. One look is enough to scare industry insiders like Aziz. Every time the equipment is run, the light source inside the equipment will undergo extremely complex refraction, reflection, and finally be poured into the laser to form a high-energy pulse.  .

    "This mechanism isisisa photolithography machine"

    A well-informed Algerian expert frowned and pondered for a moment, wondering where he had seen this set of institutions before. After thinking for a long time, his eyes finally widened and he shouted in surprise.

    "This gentleman is really well-informed. He even knows the mechanism of the lithography machine. Our nb-6600dl is not comparable to a real lithography machine. They are all abnormal-level existences that can do 193 nanometers and below. Ours  The nb-6600dl can currently only compress laser light to the level of 355 nanometers, which is still less than half."

    Before the middle-aged expert finished speaking, Zhuang Jianye came over with a smile while holding a stack of documents. As he spoke, he handed the documents in his hand to Aziz: "Mr. Aziz, this has just been processed.  The random sampling inspection results of the micro-precision process holes of the flame tube show that there are a total of 1182 holes, and there is no internal thermal stress, recast layer or crack. Of course, if you don¡¯t believe it, that is our inspection room over there, which contains information about today¡¯s world  With the most sophisticated testing equipment available, you can choose from these produced products or inspect them together.¡±

    Zhuang Jianye seemed very generous, but Aziz didn't listen to what Zhuang Jianye said at all, because his whole body was shocked by Zhuang Jianye's previous words. He didn't react until Zhuang Jianye finished speaking, and asked slowly: "  Mr. Zhuang, how far can your nb-6600dl compress the laser wavelength? 355 nanometers?"
